What is acidum formicum?
Acidum Formicum.—Formic Acid. —Formic acid derived its name from the fact that it was obtained by distillation of red ants ( Formica rufa, Linné). Doebereiner discovered, in the early part of the present century, that it could be prepared artificially by the distillation of tartaric acid, water, sulphuric acid, and black oxide of manganese.

What is spiritus formicarum?

What is the flash point of formic acid?
Formic Acid is a reagent comprised of the organic chemical formic acid that cleaves proteins into peptides at the C- or N-terminal side of an aspartate residue. Formic acid appears as a colorless liquid with a pungent odor. Flash point 156°F.
What is the boiling point of anhydrous formic acid?
Anhydrous formic acid crystallizes below 0° C. (32° F.), and, according to Attfield, boils at 105° C. (221° F.). The experiments of Jardin show that the molecule of formic acid is incapable of furnishing carbon assimilable to even the simplest cellular organisms, and solutions of formiates remain perfectly clear many months.
